Topographic Map Symbols
Topographic map symbols for historic topographic maps: “Presented here is a collection of symbols used on USGS Topographic Maps printed from the late 1890s. The styles of the symbols have changed dramatically since this time, and the beginning of their history is illustrated here. We refer to sheets in this style as Generation One or First Generation topographic sheets. These sheets were printed in black, brown, and blue inks and used lines to fill areas such as rivers, lakes and coastal areas.” Via MAPS-L.
